Method for transmitting and receiving srs in wireless communication system, and device for same

A user equipment (UE) transmitting a sounding reference signal (SRS) in a wireless communication system, the UE comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories operably connectible to the one or more processors and storing instructions to, when executed by the one or more processors, perform operations, wherein the operations comprise:
• receiving a higher layer message including configuration information related to the SRS, wherein the configuration information related to the SRS includes a plurality of configuration sets related to at least one of a number of times of transmission of the SRS, a subframe in which the SRS is transmitted, a mapping start symbol of the SRS, and/or a time duration in which the SRS is transmitted;
• receiving downlink control information (DCI) triggering the transmission of the SRS, wherein the downlink control information (DCI) includes information representing any one of the plurality of configuration sets;
• and
• transmitting the SRS based on the downlink control information (DCI),
• wherein the SRS is an aperiodic SRS (AP-SRS) and is repeatedly transmitted in a plurality of subframes via a plurality of contiguous symbols.

A device including one or more memories and one or more processors functionally connected with the one or more memories, wherein the one or more processors are configured to control the device to:

• receive a higher layer message including configuration information related to the SRS, wherein the configuration information related to the SRS includes a plurality of configuration sets related to at least one of a number of times of transmission of the SRS, a subframe in which the SRS is transmitted, a mapping start symbol of the SRS, and/or a time duration in which the SRS is transmitted;
• receive downlink control information (DCI) triggering the transmission of the SRS, wherein the downlink control information (DCI) includes information representing any one of the plurality of configuration sets;
• and
• transmit the SRS based on the downlink control information (DCI),
• wherein the SRS is an aperiodic SRS (AP-SRS) and is repeatedly transmitted in a plurality of subframes via a plurality of contiguous symbols.
